Research Notes

1. Overview

The Omron A22-FK-10M is a 22 mm flush (flat) pushbutton from Omron's A22 cylindrical (22/25-dia) pushbutton series — black, non-illuminated, momentary, with a 1 NO contact. In the A22 model code, the suffix -10M specifies the contact/operation (1 NO, momentary), so it's supplied as a unitized operator + switch. It's a general-purpose industrial panel pushbutton (IP65) with Omron's easy mount/wire design.

2. User Sentiment

The Omron A22 line is a long-standing, reliable industrial pushbutton family — valued for solid build, easy switch-unit mounting/removal, and broad availability. As a black flush momentary button it's a neutral general-function control. Practical points: confirm the contact/operation code (here 1 NO momentary) and the color code from the exact model number, and note the newer A22N series is the modular successor (operator + separate switch unit).

3. Real-World Applications

General-purpose black (neutral/function) flush momentary button on machine and control panels — start/function/general control wired through the 1 NO contact.

4. Technical Specifications

  • Type: Omron A22 flush (flat) pushbutton, 22 mm, momentary
  • Color: black (confirm A22 color letter vs catalog)
  • Contact/operation: 1 NO, momentary (per the "-10M" suffix)
  • Cutout: 22 mm
  • Sealing: IP65
  • Approvals: UL, CE

5. Ordering & Compatibility

Fits standard 22 mm cutouts. The A22 model code carries color + contact/operation (e.g. -FR- = red, -10M = 1 NO momentary). Related: illuminated A22 variants, e-stop A22E, and the modular A22N successor series. Confirm color and contact from the exact catalog number.

6. Known Issues

No notable reliability issues — a mainstream Omron pushbutton. Practical care: verify the contact/operation (1 NO momentary here) and color from the exact model, confirm the 22 mm cutout, and note the A22 (unitized) vs A22N (modular) distinction when sourcing service parts.

Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).

Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.

Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

L T 11 12 NO (open) press ↓

Depanare

Button doesn't respond when pressed

Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.

Works intermittently

Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.

Button feels mushy or doesn't click

The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
